Steering sensor pin assembly

1. An agricultural vehicle comprising:

a front axle assembly including an axle beam, said axle beam including a slot;

a wheel assembly including a steering knuckle and a wheel flange assembly, said steering knuckle coupled to said wheel flange assembly; and

a steering sensor pin assembly including:

a steering sensor pin having a first end and a second end opposite said first end, wherein said second end has a flat face;

a kingpin connected to said steering knuckle, said kingpin having a top surface, a bottom surface, and a hole from said top surface to said bottom surface, said hole aligned with said slot in said axle beam, and wherein said steering sensor pin is positioned in said hole for coupling said kingpin to said axle beam via said flat face of said steering sensor pin coupled with said slot.

2. The agricultural vehicle according to claim 1 , wherein said slot is formed in said axle beam, said slot having a slot side surface and a slot bottom surface.

3. The agricultural vehicle according to claim 2 , wherein said slot side surface is thread-less.

4. The agricultural vehicle according to claim 1 , wherein said steering sensor pin is thread-less.

5. The agricultural vehicle according to claim 1 , wherein said steering sensor pin is configured with a notch, said steering sensor pin including an O-ring seated in said notch.

6. The agricultural vehicle according to claim 1 , wherein said steering sensor pin assembly further comprises a steering sensor, and wherein said steering sensor is connected to a region of said top surface circumferentially adjacent to said hole for encapsulating said steering sensor pin in said hole.

7. The agricultural vehicle according to claim 6 , wherein said kingpin further comprises a top portion including said top surface and a bottom portion including said bottom surface, said bottom portion further including a bottom portion side surface and a tapered roller bearing assembly arranged circumferentially on said bottom portion side surface, wherein said axle beam has an opening having an opening bottom surface and an opening side surface, wherein said slot is formed in said opening bottom surface, and wherein said bottom portion of said kingpin is positioned in said opening such that said tapered roller bearing assembly contacts said opening side surface of said axle beam for enabling rotation of said kingpin, said connected steering sensor and said connected steering knuckle about said steering sensor pin.

8. The agricultural vehicle according to claim 7 , wherein said steering sensor is configured to generate an electrical signal based upon an angle of rotation of said steering sensor about said steering sensor pin.

9. The agricultural vehicle according to claim 8 , wherein said angle of rotation of said steering sensor about said steering sensor pin is measured with respect to a reference line that is normal to said flat face of said steering sensor pin.

10. The agricultural vehicle according to claim 7 , wherein said top portion of said kingpin is connected to said steering knuckle.

11. The agricultural vehicle according to claim 10 , wherein said top portion of said kingpin is connected to said steering knuckle via fasteners or welds.

12. The agricultural vehicle according to claim 7 , wherein said front axle assembly further comprises at least one tie rod, and wherein said at least one tie rod is coupled to said steering knuckle for rotating said steering knuckle, said connected kingpin and said connected steering sensor about said steering sensor pin.

13. The agricultural vehicle according to claim 1 , wherein the agricultural vehicle is a tractor.
